An Improved MTPA Control Based on Amplitude-Adjustable Square Wave Injection
IEEE transactions on energy conversion, 2020In traditional maximum torque per ampere (MTPA) method based on signal injection, fixed wave amplitude and constant integral coefficient are employed, which actually degrade the optimal current angle tracking performance in variable conditions ...

Neurology, 1982
Abnormal saccadic intrusions consisting of frequent sporadic horizontal saccades followed, after an interval, by corrective saccades occurred in 70% of 17 patients with acute or chronic focal cerebral lesions. These square wave jerks were significantly lower in amplitude than those in cerebellar system disease.

Quantitative eye movement recordings in a patient with multiple sclerosis who had both macro square wave jerks and an internuclear ophthalmoparesis supported the concept of an internal brain-stem monitor that mediates corrective eye movements. A brain-stem model of this monitor illustrates the patient's motility disorder and the normal function of ...

A Method of Resolver-to-Digital Conversion Based on Square Wave Excitation
IEEE transactions on industrial electronics (1982. Print), 2018A novel method of resolver-to-digital conversion based on square wave excitation is proposed in this paper. First, the outputs of the resolver under square wave excitation are theoretically analyzed in comparison with those under cosine excitation ...

This paper concerns square wave analysis, which is in no small part a generalization of the Fourier analysis based on sine and cosine functions. Following sine and cosine functions square waves become another frequently used and easily generated waveform in electronics, so it is an urgent practical problem to study the basic properties of square waves ...

A method is described for eliminating the undesirable effect of the double-layer capacity current on the sensitivity of an A.C. polarograph. A square-wave voltage is used in place of the usual sinusoidal polarising voltage, and the amplitude of the A.C.
